Psychological functioning and quality of life (QOL) will also be evaluated to monitor participants' emotional status throughout the trial. The Patient Health Questionnaire-9 and the Generalized Anxiety Disorder-7 questionnaires will be used to assess depression and anxiety, respectively. If any participant endorses suicidal ideation on the PHQ-9, the Suicide Behaviors Questionnaire-Revised (SBQ-R) will be administered to fully evaluate the participant's suicidal ideation and study stopping rules will be implemented as needed to ensure the individual's safety. QOL will be evaluated by the Quality of Life in Alzheimer's disease (QOL-AD) and Quality of Life in Late-stage Dementia (QUALID) and Everyday Cognition (ECog) questionnaires (patient and caregiver forms).
